SolidBSP [hull 0] 20 (0.00 seconds)Warning: === LEAK in hull 0 ===Entity light_environment @ ( 128, -64, -96)Error: A LEAK is a hole in the map, where the inside of it is exposed to the(unwanted) outside region. The entity listed in the error is just a helpfulindication of where the beginning of the leak pointfile starts, so thebeginning of the line can be quickly found and traced to until reaching theoutside. Unless this entity is accidentally on the outside of the map, itprobably should not be deleted. Some complex rotating objects entities needtheir origins outside the map. To deal with these, just enclose the originbrush with a solid world brush
